Direct Torque Control of Permanent Magnet Synchronous Motor

Direct Torque Control of Permanent Magnet Synchronous Motor (PMSM) – MATLAB/Simulink Project

This project presents the MATLAB/Simulink implementation of Direct Torque Control (DTC) for a Permanent Magnet Synchronous Motor (PMSM), focusing on high-performance motor drive applications. The DTC strategy directly controls the electromagnetic torque and stator flux of the PMSM without requiring complex coordinate transformations or current regulators, resulting in a fast dynamic response and robust control.

The developed model includes a PMSM drive system, voltage source inverter (VSI), hysteresis controllers, torque and flux estimators, and switching logic. The simulation demonstrates effective torque control, reduced response time, and improved system stability under varying speed and load conditions.

This project is ideal for students, researchers, and engineers working in electric drives, electric vehicles, robotics, and industrial automation. It serves as a practical reference for understanding advanced motor control techniques and implementing them using MATLAB/Simulink.
